Photosynthesis

Storage of nutrients

Transporting water and minerals

Transporting food (plant sugars)

Providing structural support

They only grow a single stem and have scattered vascular tissue bundles.

They are often branched and woody.

They contain multiple stems and vascular bundles arranged in rings.

They grow wider with age.

Growth is redirected to other meristems.

The plant dies.

The plant stops growing taller.

The vascular bundles scatter throughout the tissue.

Monoecious plants have both male and female flowers on a single plant, while dioecious plants have male and female flowers on separate plants.

Monoecious plants have only male flowers, while dioecious plants have only female flowers.

Monoecious plants grow faster than dioecious plants.

Dioecious plants can self-pollinate, while monoecious plants cannot.
